To all whom it may concern.

a citizen ofthe United States, residing at Kushequa, McKean-county, Pennsylvania, have invented certain new and useful Improvements inBrick, Block, or Tile Cutters or Shapers and I do hereby declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the. art to which it apper- This invention relates to certain improvements in brick, block or tile cutters, and relates more particularly to improvements in machines for producing special or peculiar shapes for use in construction or other work, and the objects andnatureof the-invention will be readily understood by those skilled in the art in the light of the following explanation of the structure shown by the accompanying drawings as my preferred embodiment from among other structures within the spirit and scope of my invention. 5

The invention consists in certain novel features in construction or in combinations andarrangements of parts as more fully and particularly set forth hereinafter. I

An object of the invention is to provide im- 7 proved means whereby bricks, blocks or tile of regular or standard sizes suchas produced by machines or by hand, can be easily out before drying and burning, to produce various special shapes or forms such as are often requiredin construction and other work.

A further object of the invention is to provide a brick, block or tile cutter embodying several cutting wires or other blades and actuating means therefor capable of varied'adjustments within a, wide range whereby either wire or blade can be arranged at any desired angle or position with respect to the work, orwhereby the two wires or blades can be adjusted relativelyto any desired position or angle, or can be brought into parallelism at a greater or less distance apart, all for the purpose of producing special shapes and forms from regular stock or standard sizes of brick or the like while in the green condition. I Referring to the accomp anying drawings Figure 1, is a front elevation of the machine. Fig. 2, is a top plan view thereof. Fig. 3, is a partial longitudinal vertical section. Figs. 4 and 5, are horizontal sectional plans showing the cutting wires and gages or stops invarious adjustments. Fig.- 6,-is a horizonta section on theline 66,"Fig. 1. q I

I In the drawings, I show a flat top table 1, Be it known that I, WILLIAMIHENRY HILL, I

supported by suitable legs or standards 2-.

In the specific example illustrated, I show the table top formedwith an opening occupied by a usually removable plate, frame or platform 4, resting on a depressed seat 3, with its top face preferably flush with the upper face'of the tabletop. This platform 4, forms or carries the. laten 5, on which the blocks or other artio es rest while being cut or shaped to produce the desired special forms.

In the specific example illustrated, the platform 4, is shown formed with a pair of parallel transverse elongated slots 6, opening therethrough and extending substantially throughout the width of the platform 011 opposite sides of the platen 5, which is arranged between said slots. Each slot 6, forms a slideway for arpair of vertically arranged tubular guides or vertical guide sleeves 7, hav ing opposite horizontal flanges 8, engaging the upper and lower faces of the edge portions of the platform 4, along said slots to permit and to hold the same therein against vertical movement, as will be readily understood.

Inthe specific example illustrated, I show four guides 7, two in each slot, each adjustcentral portion of the slot. Each guide is adjusted longitudinally of its slot and is held in the desiredadjustmentby a horizontal adjusting screw 9, arranged beneath and transversely of the table top and platform and passing through a normally fixed nut 10, and at its outer end having suitable turning means, such as handle 11, accessible beside the table, and at its headed inner end 12, loosely and detachably confined to 0 en bottom socket projecting laterally om the lower portion of its guide 7, to rotate therein and yet so as to move the guide longitudinally in either direction in the slideway with the threaded rod'or screw. The sockets 70 are so formed with open bottoms that the platform 4, can be lifted from the table with its guides 7, and the sockets will move up therewith from the heads 120f the screws.

I Vertical slide rods or posts 13, extend through and reciprocate vertically in said guides, each guide receiving a rod. At their lower ends, the rods are secured to a horizontally disposed s ider frame through the medium of which a of the slide rods are simultaneously reciprocated.

able from one end thereof to and from the any guide 7, to slide longitudinally of its slot In the specific example illustrated, the spider frame comprises two parallel bars 14, arranged below and in the planes of the platform slideways, respectively, and these bars 14, are longitudinally slotted to receive the lower ends of the slide rods and ermit adjustment of said rods longitudina ly of said bars by the movement of the guides in the platform slideways. These two bars 14, of the horizontal bottom spider frame are rigidly secured together by a center cross piece 15. The slide rods carry the cutting wires 16, or any other suitable cutting blades, arranged horizontally and transversely above the platform and platen hereinbefore described. Each wire 16, is carried by a pair of slide rods, usually by slide rods arranged at corresponding end portions of opposite slideways so that the cutting wires extend transversely of and above intermediate por tions of the platen; normally above the opposite end portions of the platen. Each wire is stretched between its slide rods and removably attached thereto usually a distance below the upper ends of the rods, in any suitable manner so that the wires can be readily removed and replaced in the event of breakage. For instance, each wire can be headed at one end and pass removably through one slide rod and at its opposite end be removably secured to an adjustable hook 17, secured to the opposite slide rod by means of which the wire can be kept taut or under the desired tension. Each pair of slide rods, carrying a cutting wire, can be connected at their upper ends by a cross link or plate 18, having end longitudinal slots 19, receiving the upper ends of the slide rods.

Each slide rod can be provided with a head 20, at its lower end engaging the under face of the spider frame bar through which said rod passes, and can be threaded at its upper end to receive a thumb or other nut 21, adapted to screw down on and clamp the rod and cross link 18, rigidly together and the lower end of the rod rigidly in the desired adjustment in the spider frame. To attain this clamping action, an exterior spacing sleeve or tube 22, can be arranged on the rod, at its upper end abutting against the under face of the cross link and at its lower end abutting against the upper face of the spider frame.

Any suitable power or manually actuated means can be employed to vertically reciprocate the slide rods and thereby move the cutting wires down to the platen to perform the cutting stroke and raise the same on the return stroke. For instance, I show a vertically swinging foot treadle 23, fulcrumed at 24, and having foot pedal 25, beyond the front end of the table. Intermediate its length, this treadle is adjustably and removably coupled to the cross frame of carrying device of the cutting wires, by link 26. Counter weight mechanism. 27, can be provided to yieldingly and normally hold the treadle and cutting wires and their supports in elevated positions and to return the same to such )ositions after completion of a cutting stroke.

On loosening the thumb nuts at the upper ends of the slide rods, the rods of a pair can be moved by the screws and guides to or from the longitudinal center line of the platen to carry the cutting wire of such rods to a )OSh tion parallel with or at any desired angle to said center line and at the desired distance therefrom. The slide rods of the other cutting wire can, likewise, be independently adjusted to any desired position parallel with or at an angle to said center line, or to any desired position with respect to the first named cutting wire. The slide rods and wires can then be clamped and locked in the desired adjustments by the thumb nuts.

The wires can be adjusted to any desired position with respect to each other to simultaneously cut opposite portions of the same piece of work, one wire can be moved back from over the portion of the platen occupied by the work so that the other wire can do the work where one out only on each piece of work is necessary to produce the form desired.

The wires can be so adjusted, and the pieces of work can be so arranged on the platen with respect to the wires, as to produce an almost infinite variety of forms and shapes from. the ordinary standard or stock shape brick or block while in the green condition. Tiles and other clay, cement, or the like articles, while green can also be cut to special shape or form.

In order to hold the work on the platen in the desired position with respect to the wires to produce the form desired, I provide vari ous adjustable stops or gages. For instance, 28, are a pair of separate gages usually employed over the surface of the platen between the two wires and adjustable to any angle with respect to the wires and longitudinally on the platen. Each gage 28, has an elongated longitudinally slotted shank and is secured by a removable clamp 29, to one of the slides 7, for instance. I also show a main or end gage 30 extending from. the table top onto the platen between the two slide ays in the platform. This gage is formed with a T-shaped slot in its shank or body receiving a clampin bolt, rising from the table top and having clamping nut 31, for locking the gage in the desired position and adjustment.

It is evident that various changes and. modifications might be resorted to in the forms, constructions and arrangements of the parts described and that parts might be omitted or elements added without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact constructions set forth.
